ABSTRACT
Objective:
To determine the contents of paraceltamol and caffeine in New compouad Folium Isatidis Tablets simultaneously by HPLC.Methods:
The determination was carried out with C 18 chemical bonded silica gel as a solid phase, methanol-water (25∶75) as a mobile phase and UV deterction wavelength at 215 nm.Results:
The average recovenies of the added sample were 99.6%( RSD=0.67, n=5) for paracetamol and 99.3%(RSD=0.58, n=5) for caffine, There was a good linear relationship between the concentration and absorption area value in the rang of 1.6?g~6.4?g for paractamol or 0.16?g~0.64?g for caffeine.Conclusions:
The method is simple, quick and accurate.
